Hello,
I wanted to know how much kernel and userspace memory is available on the
Linux system during run-time either by some C code or some procfile.
Do you know how to do that?
Thanks,
Dev

have you checked /proc/meminfo and its handler?

You can look in /proc/meminfo
http://unixfoo.blogspot.com/2008/02/know-about-procmeminfo.html
The memory is shared between userspace and kernel space and the amount
of memory available changes dynamically as the system is running.
Be aware that Cached memory is quite dynamic, and the system will
throw away cache pages to make space if it needs to.
